The Efficacy of Greater Occipital Nerve Block in Patients With Chronic Migraine

Aim : In chronic migraines(CM), the rate of benefiting from medical treatment is relatively low, and it is known that patients use analgesics extensively. Greater occipital nerve (GON) block, have been started to be used in chronic migraine patients who were refractory to treatment. In this study, we aimed to evaluate the headache attack frequency, analgesic use, VAS (Visual Analog Scale) and MIDAS (Migraine Disability Assessment Scale) scores in the 3-month follow-up of patients we had performed a GON block in our clinic for chronic migraine refractory to medical treatment. Materials and Methods: A total of 120 CM patients were included in the study. The number of analgesics used, the number of days with pain, and the VAS and MIDAS scores were recorded before the GON block and at one and three months of treatment. Results: There was a statistically significant (p
